    <p>Sorry to switch languages here, but I got this to work well in Ruby using <a href="https://github.com/arsduo/koala" rel="nofollow">Koala</a>. I'm using a <a href="https://developers.facebook.com/docs/reference/api/batch/" rel="nofollow">Batch Request</a> as follows:</p> <pre><code> friends = @graph_batch.batch do |batch_api| batch_api.get_connections("me", "friends", {:limit =&gt; 100, :offset =&gt; 0}, :batch_args =&gt; {:name =&gt; "get-friends"}) batch_api.get_objects("{result=get-friends:$.data.*.id}") batch_api.graph_call("method/fql.query", { :query =&gt; "SELECT uid1, uid2 FROM friend WHERE uid2 IN ({result=get-friends:$.data.*.id}) AND uid1 IN (SELECT uid2 FROM friend WHERE uid1=me())" }, "post" ) end </code></pre> <p>That is,</p> <ol> <li>Graph - Get my friends list - /me/friends</li> <li>Graph - Get my friends data - /?ids={result=get-friends:$.data.*.id}</li> <li>FQL - Get all mutual friends - /method/fql.query?query=SELECT uid1, uid2 FROM friend WHERE uid2 IN ({result=get-friends:$.data.*.id}) AND uid1 IN (SELECT uid2 FROM friend WHERE uid1=me())" } <strong>(with proper escaping and POST method)</strong></li> </ol> <p>The third query will return a list of elements, uid1, uid2. From there, you have all the data you need to calculate mutual friend counts. In Ruby, I use the following:</p> <pre><code> friends[2].clone.delete_if { |r| r['uid2'] != "xxxxxxx" }.count </code></pre> <p>Basically, I count all elements in the array where uid2 is a specific ID. I'm sure there's better ways to count, but the data is now yours. Hope this helps, and sorry again for switching languages on you (but what's a language mean when you're using an API anyway?). </p> <p><strong>Edit</strong>: You'll only be able to do about 100 rows at a time. You can adjust the limit / offset parameters to page through results.</p>

    1. COthis is what I ended up doing using FQL, but now the problem is that you end up hitting a row limit and the query won't finish completely.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
